STEAM CLEANER- JFQR MOTORS.

Application filed November 17, 1923. Serial No. 675,376.

a useful Improvements in Steam Cleaners for Motors, of which thefollowing is a specification. L

This invention relates to steam cleaners for motors andhas particular reference to means for creating a jet of steam for the purpose of blowing the same through the cylinders to clean out the carbon therein.

Another object is to produce a device of this character which is simple in construction, cheap to manufacture, and well within the purchase price of the average user.

Another object is to produce a device which may be attached to any automobile now upon the market without materially altering the construction of the same.

Other 0 jects and advantages will be apparent d ring the course of the following .descri ti n.

In t e accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

The figure is a side elevation of a motor having my device attached thereon.

It'is a well-known fact that live steam driven through the cylinders of an internal combustion engine will'clean out and blow out the carbon which maybe deposited there'- in. I have sought to provide means whereby steam maybe quickly generated and blown through the various cylinders, as desired.

In the accompanying drawin wherein for the purpose of illustration is shown a preferred'embodiment of my invention, the numeral 5 designates a motor as a whole having an exhaust pipe 6. This exhaust pipe is connected to the usual exhaust ports 7, 8, 9 and 11, while the customary spark plugs 12 and 13 serve to ignite the charge in two of the cylinders, while in the drawing the spark plugs in two of the other cylinders have been removed and auxiliary valves 14 and 16 have been inserted in their place. It v is of course obvious thata spark plug oi the type having a port and valve incorporated therein would eliminate the necessity of removinglthe spark plug.

To t e lower'end of the exhaust pipe or exhaust manifold is attached a -casting, which casting has a passageway 18 extending directly therethrough and in line with the bore of the exhaust manifold. A chamber 19 is oiiset from the passageway 18 and has access thereto through the medium of ports 21 and 22. These ports may be closed by flap valves 23 and 24:.

A coil preferably made of copper is positioned in the chamber 19 and bears the numeral 26. This coil has its. lower extremity connected by a pipe 27 to a T fitting 28. This T is also connected to a reservoir 29 and has its other connection extending by a pipe 31. to the valve 16. ,The opposite end of the coil 26 is connected by a pipe 32 to the valve 14.

The operation of my device is as follows -When it is desired to clean a cylinder the fiap' valves 23 and 24 are moved into the position shown in the figure. The engine is then started, with the result that the exhaust from the left-hand cylinders will be conducted from the exhaust manifold through the chamber-19 around the coil 26 to the pipe 27 and at the same time a small amount of liquid will be taken from the reservoir 29 and shot into the hot coil 26, thus forminga super-heated'steam which will then pass to the-cylinder having the valve 14 secured thereto.

When it is desired to clean the other cylinders the pipes 31 and 32 will be removed tothe respective cylinders. When desiring to remove dirt or so from the "out: side of the motor, disconnect the pipe 32 and then connect the steam hose.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that variouschanges in the shape, size and arrangement of parts may be resorted'to without departing from the spirit of the invention or the scope of the, subjoined claims. i

Having'thus described my invention, I claim .5

1. In a device of the character described, thecombination with a motor, a casting adapted to be secured to the exhaust manifold; of said motor, saidcasting having a the combination with an internal combustion engine having an exhaust manifold, a casting secured to said manifold and adapted to receive the exhaust therefrom, a passageway formed in said casting, a chamber formed in said casting, ports formed in said chamber and communicating with said passage, flap valves adapted to close said ports, a coil mounted in said chamber, and means for conducting a vapor to and away from said coil, for the purpose specified.

modem 3. Jim a device of the character described the combination with an engine of the internal combustion type, means for conducting a jet of steam to the cylinders of said engine individually, said means comprising a coil, a receptacle adapted to contain a quantity of fluid, means for conducting a small portion of said fluid to said coil, means for conducting said fluid from said coil to said cylinders independently, and means for heating said coils from the exhaust of said cylinders, substantially as and "for the purpose specified.

In testimony whereof I allix my signature.
